Rigging: Arm moves the pants even though it has no weight
I finnaly figured out how to solve this, i hope this helps someone with the same problem.



what i did was i deleted all vertex groups that corresponded to the upper body inside the pants mesh, if i go to weight mode you can see that its purple because it has no vertex assigned as the arm in the pants mesh. somehow removing weight wasnt working so this was the only way i could solve that.
